I think the lesson here, as has been so eloquently stated, go with what works, ferinstance;
I shave with a brush, shaving soap and a straight razor. I’ve had the same cake of sandalwood shaving soap for three and a half years, and I shave thrice during a week. Much of the shaving soap has been made the same way since the early 1900’s, and the makers arent about to change.
Deodorant, is deodorant, is deodorant. You want one that doesn’t ever, ever change? Find one that is a scent match to your cologne (if you wear it). The scents mingle, and the formulation doesn’t change.
If you don’t wear cologne, start. Find a good one, and stick with it. As a general rule, women love men that smell good. Don’t be afraid boys, it’s 2005.
I wear boxers when I can, and boxer briefs when I can’t (like when I’m at work or weaing a kilt). Boxers have been boxers since they were invented. Tighty whities are for 8-year olds. Again, if you don’t want anyone messin’ with your underoos, buy them where you buy suits (even if you don’t buy suits) clothiers, as opposed to chain retail stores cater to men who abhor changes in their gear, and will likely have the same underwear on the rack in 10 years that they do today.
Shampoo and soap: Guys, go to a beauty supply house. Buy your unscented shampoo a gallon at a time. Odds are, it won’t change a lick, because the customers (i.e salons) won’t buy the stuff if it does. I enjoy good soap that has a good scent, and is good for my skin. I found some on a vacation to St. Maarten a few years back (it was the hotel soap), and it’s all I use. It’s been the same soap since 1934, only today, there’s gel.
I’m with the OP in spirit, but there’s an easy way to solve his dilemmas. Trade up. It will cost you a little more, but the frustration will evaporate. The problem is, in this disposable world we live in, that consumers can never expect to find the same thing for a very long period of time, since to make the margins, companies that do business with mass retail chains try to make ‘improvements’ to their products, and because Joe Six Pack eats up that ‘new and improved’ drivel, OP’s like this one are born.
A bit of sage wisdom from a very old and dear friend of mine;
Buy the best you can afford, and when you can afford better, buy it, you’ll never go wrong.
